Reliable water quality checks need a meter that is easy to carry, clear to read and ready for changing measurement tasks. This portable conductivity meter supports conductivity, liquid resistivity, TDS, salinity and temperature measurement with combined 4-ring or 2-ring conductivity/temperature probes.
Use it in field work, laboratories or water-related process checks where stable, documented readings matter. Automatic calibration with 147 µS/cm, 1413 µS/cm, 12880 µS/cm and 111800 µS/cm standard solutions reduces setup effort, while selectable temperature compensation from 0.00 to 4.00%/°C helps align readings to the sample behavior.
The IP66-protected ABS and rubber housing is built for mobile use. Both models transfer real-time measurements via RS232C, and the HD2106.2 adds USB 2.0 connection plus memory for up to 36,000 conductivity and temperature samples.
The instruments work with combined 4-ring and 2-ring conductivity/temperature probes, as well as Pt100 or Pt1000 probes for temperature-only measurement.
Conductivity readings can be compensated automatically or manually from 0…100 °C, with selectable αT from 0.00 to 4.00%/°C and reference temperature of 20 °C or 25 °C.
The meter calculates maximum, minimum and average values and includes relative measurement, Auto-HOLD and automatic turn-off, which can also be disabled.
Both models include an electrically isolated RS232C serial port for real-time transfer to a PC or portable printer. HD2106.2 also provides USB 2.0 communication.
HD2106.2 records up to 2,000 pages with 18 samples each. The storage interval is selectable from 1 second to 1 hour.
The LCD shows the selected conductivity-related parameter and temperature together, with 2x4½ digits plus symbols and a visible area of 52x42 mm.
